Abstract: The present disclosure relates to a hydrolysate of a mixture of lignocellulosic biomass and seaweed biomass. By mixing seaweed biomass with lignocellulosic biomass and then preparing a hydrolysate, lignocellulosic biomass-derived acetic acid is consumed together with seaweed biomass-derived mannitol. As a result, high sugar productivity can be maintained while reducing fermentation inhibitors. Because the present disclosure can solve the problem of lignocellulosic biomass of decreased fermentation efficiency due to lignocellulose-derived fermentation inhibitors and the problem of seaweed biomass of very low productivity in spite of long fermentation time, the hydrolysate according to the present disclosure may be used to produce biofuels and biochemicals economically.

Abstract translation: 本公开涉及木质纤维素生物质和海藻生物质的混合物的水解产物。 通过将海藻生物质与木质纤维素生物质混合，然后制备水解产物，木质纤维素生物质衍生的乙酸与海藻生物质衍生的甘露醇一起消耗。 因此，可以在减少发酵抑制剂的同时保持高的糖生产率。 因为本公开可以解决由于木素纤维素衍生的发酵抑制剂引起的发酵效率降低的木质纤维素生物质的问题和尽管发酵时间长的生产效率非常低的海藻生物质的问题，但根据本公开的水解产物可用于 经济地生产生物燃料和生物化学品。
